The secret was revealed Tuesday by The Real co-host Tamar Braxton.

For days, people have been wondering who shouted out “Haay, Michelle” to the First Lady at last week’s Black History Month celebration.

The shout-out came during a packed reception in the East Room of the White House and no one was able to identify the bold voice. Well, the secret was revealed Tuesday by The Real co-host Tamar Braxton, who said it was her sister, Traci.

“Lord have mercy, my sister, Traci, done made a little Black History of her own,” she said before Tuesday’s big reveal, which actually came to light because of their mom, Evelyn, who figured it out.

“I was like for real? She’s like for real,” Tamar said recalling the conversation with her mom. “And then somebody played it for me. I said, ‘Oh my God, that’s my sister!’”
